  • Secured a series of victories on behalf of Sandoz Inc. in the first case to interpret the Affordable Care Act’s Biologics Price Competition and Innovation Act (BPCIA). The federal district court ruled in Sandoz’s favor on all issues before the court, adopting Sandoz’s interpretation of the BPCIA in all respects. The court also denied Amgen’s motions urging a contrary interpretation and seeking a preliminary injunction. The Supreme Court ruled in Sandoz’s favor on appeal. In further litigation on the asserted patents, the district court adopted Sandoz’s claim constructions on Amgen’s method of treatment patent, which resulted in Amgen stipulating to noninfringement of that patent. The court then granted Sandoz’s motion for summary judgment of noninfringement on the remaining patent directed to purification of proteins expressed using recombinant DNA technology. The Federal Circuit affirmed Sandoz’s victory on both patents.

  • Represented the world’s largest maker of DNA sequencing systems, Applied Biosystems (AB), against one of its biggest competitors, Illumina, seeking a declaratory judgment that AB’s newest DNA sequencing system did not infringe patents held by Illumina and that the patents were invalid. The patents involved biotechnology, electronics, and software elements. AB prevailed on a key summary judgment ruling of noninfringement on one of the four asserted claims. During trial, AB eliminated one other claim as invalid and another as not infringed. After a three-week trial, the jury agreed that AB’s probes did not infringe the remaining claim. All rulings were affirmed on appeal.

  • Won a preliminary injunction on behalf of medical device company Nevro, protecting its high-frequency spinal cord stimulation technology against infringement by competitor Stimwave.
